Description

Technical Field

[0001] This invention relates to the field of equipment packaging technology, specifically to a cushioning packaging structure and a packaging box for a gas-fired heating hot water boiler. Background Technology

[0002] The purpose of packaging foam is to support and fill products such as hot water heaters and wall-mounted boilers inside the packaging carton, and to cushion and protect them during loading, unloading and transportation, ensuring that the products are not damaged before they reach consumers.

[0003] The foam material used in traditional techniques is EPS polystyrene, with a density of 15-20 kg / m³. 3 Foam structures often tightly wrap the product in two parts, preventing the impact energy from dissipating when subjected to impact. This results in poor impact resistance and cushioning, and the foam comes into direct contact with relatively fragile parts of the product. For example, the foam may come into contact with the electrical control box of the wall-hung boiler, the flue of the exposed part of the fan, and the bottom tray of the water pipe. These fragile parts that come into direct contact with the foam are subjected to significant drop impacts, bumps, and compression during the complex logistics process of loading, unloading, and transportation. This can easily cause product deformation and damage, resulting in direct economic losses for product manufacturers and logistics providers, and reducing end consumers' confidence in the product brand.

[0004] In addition, existing foam structures use a lot of materials, which accounts for a high proportion of the packaging material cost. They are also heavy and bulky, resulting in high transportation and storage costs. Furthermore, foam structures require differentiating between front, back, left, and right during packaging operations, which causes inconvenience, increases labor costs, and makes it difficult to automate the process. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, one of the objectives of this invention is to provide a cushioning packaging structure that solves the above-mentioned traditional problems. It has the effects of absorbing and decomposing energy, and improves its shock-absorbing and protective performance.

[0006] The second objective of this invention is to provide a packaging box for a gas-fired heating hot water boiler that uses this cushioning packaging structure.

[0007] One of the objectives of this invention is achieved through the following technical solution:

[0008] A cushioning packaging structure includes a first foam, a second foam, and a side foam disposed between the first foam and the second foam, wherein the first foam, the second foam, and the side foam form an accommodating space.

[0009] Preferably, the first foam includes a base body, a plurality of first abutment blocks and second abutment blocks extending outward from the base body; each of the first abutment blocks is disposed on the four corners of the base body, and the second abutment blocks are respectively disposed on opposite sides of the base body.

[0010] Preferably, the bottom body has multiple sets of buffer bumps protruding on the side facing the second foam, and each set of buffer bumps is arranged along one end of the bottom body to the other end.

[0011] Preferably, the buffer bump group consists of multiple evenly distributed cylinders with arc-shaped tops.

[0012] Preferably, the first abutting block has an abutting protrusion facing inward, and the width of the abutting protrusion is smaller than the width of one side of the first abutting block.

[0013] Preferably, the first abutment block has a first hollow hole located at the intersection of the two sides.

[0014] Preferably, the structure of the second foam is the same as that of the first foam.

[0015] Preferably, the side foam includes a side body and an abutment block extending outward from the end of the side body. The side body is provided with a plurality of buffer grooves, which are arranged along one end of the side body to the other end. The abutment block abuts against the first foam and the second foam, and the abutment block is provided with at least one second hollow hole.

[0016] Preferably, the buffer groove is a strip groove with an outwardly expanding structure.

[0017] The second objective of this invention is achieved by the following technical solution:

[0018] A packaging box for a gas-fired heating and hot water boiler is provided for packaging the gas-fired heating and hot water boiler. The packaging box includes a box body and the aforementioned cushioning packaging structure, which is housed within the box body.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. The cushioning packaging structure of the present invention provides protective packaging for the product through the containment space formed by the first foam, the second foam and the side foam. When the first foam is impacted, the impact energy can be absorbed and decomposed through the transition of the side foam, thereby reducing the impact energy when the front, back and sides of the product are impacted. At the same time, the packaging structure is divided into individual foams, making it easy to store and transport.

[0021] 2. The cushioning packaging structure of the present invention has a first perforation on the first foam and the second foam, and a second perforation on the side foam. When subjected to external impact, the deformation of the foam can absorb and decompose the impact energy, thereby further improving its impact-resistant cushioning protection performance.

[0022] 3. The cushioning packaging structure of the present invention reduces the area of ​​direct contact between fragile parts and foam by providing cushioning bumps on the first foam and the second foam, thereby reducing the damage to the product caused by impact.

[0023] 4. The cushioning packaging structure of the present invention has cushioning grooves, especially trapezoidal grooves, on the side foam, which makes it easier to collapse and absorb energy, thereby reducing the damage to the side of the product when it is subjected to physical impact.

[0024] 5. The cushioning packaging structure of the present invention uses a first foam and a second foam that are symmetrically arranged. At the same time, the holes, grooves, and clearance spaces in each foam are also symmetrically arranged, which facilitates packaging operations, eliminates the need to distinguish between front, back, top, bottom, left, and right, and prevents incorrect foam installation. It also has a foolproof function, which reduces the cost of producing foam materials and provides better protection for products in complex logistics and transportation environments, improves quality, and thus improves customer satisfaction.

[0035] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] In the description of this invention, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0037] In the description of this invention, it should be understood that when an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be intermediate elements present. Conversely, when an element is referred to as being "directly" connected to another element, there are no intermediate elements.

[0038] Please see Figures 1-6 The present invention provides a preferred embodiment of a cushioning packaging structure for packaging products such as gas-fired heating water heaters or hot water boilers. The cushioning packaging structure includes a first foam 10, a second foam 20, and a side foam 30 disposed between the first foam 10 and the second foam 20. The first foam 10, the second foam 20, and the side foam 30 form a storage space for accommodating the product, thus providing protective packaging for the product. When the first foam 10 is impacted, the impact energy can be absorbed and decomposed through the transition of the side foam 30, thereby reducing the impact energy when the front, back, and sides of the product are impacted. At the same time, the packaging structure is divided into individual foams, making it easy to store and transport.

[0039] Specifically, both the first foam 10 and the second foam 20 are used to protect the front and back of the product. For example... Figure 3 and Figure 4As shown, the first foam 10 includes a base body 11 and a plurality of first abutment blocks 12 and second abutment blocks 13 extending outward from the base body 11. Each first abutment block 12 is located at one of the four corners of the base body 11, and the second abutment blocks 13 are located on opposite sides of the base body 11. These abutment blocks support the accommodating space and effectively protect the corners, edges, and surfaces of the product while reducing material usage. A first clearance 120 is provided between adjacent first abutment blocks 12 at the same end to avoid direct contact with relatively fragile parts of the product. A second clearance 121 is provided between the first abutment block 12 and the second abutment block 13 on the same side to enhance the impact-resistant cushioning capacity of the middle part of the first foam 10 and can also be used for the entry and exit of robotic arms to achieve automated product operation. A buffer space 14 communicating with the first clearance 120 is provided at the end of the base body 11. The buffer space 14 is approximately trapezoidal in shape.

[0040] To further improve the impact resistance and cushioning capacity of the first foam 10, in one embodiment, the bottom body 11 has multiple sets of cushioning protrusions 15 protruding on the side facing the second foam 20. Each set of cushioning protrusions 15 is arranged along one end of the bottom body 11 to the other end. Each set of cushioning protrusions 15 consists of multiple evenly distributed cylinders with arc-shaped tops. In this embodiment, there are four sets of cushioning protrusions 15, and each set of cushioning protrusions 15 contains four cylinders. The first abutment block 12 is approximately L-shaped with the same length at both ends. The first abutment block 12 has a circular first hollow hole 122 located at the intersection of the two sides of the first abutment block 12. This hole is used to absorb and decompose the internal energy of the first abutment block 12 when the product is subjected to a large drop impact during loading and unloading. Optionally, the first abutment block 12 has an inwardly facing abutment protrusion 123. The width of the abutment protrusion 123 is smaller than the width of one side of the first abutment block 12, so that the first abutment block 12 has a stepped groove inside, which can reduce the contact area between the product and the first abutment block 12 and further improve its impact resistance and cushioning ability. Optionally, the width of the abutment protrusion 123 is 1 / 4 to 1 / 2 of the width of one side of the first abutment block 12. In this embodiment, the width of the abutment protrusion 123 is 1 / 3 of the width of one side of the first abutment block 12. The second abutment block 13 is generally rectangular, and the extension length of the second abutment block 13 is equal to the extension length of the first abutment block 12, which reduces the material while distributing the force evenly.

[0041] Optionally, the side of the base body 11 facing the second foam 20 is further provided with a first clearance cavity 16 and a second clearance cavity 17 arranged opposite to each other. The first clearance cavity 16 is generally square in shape, and a third clearance cavity 160, which is circular in shape and located near the end of the base body 11, is provided inside the first clearance cavity 16. The third clearance cavity 160 is connected to the first clearance cavity 16, and there are three third clearance cavities 160, which are used to provide clearance for the electronic control part of the product. The structure of the second clearance cavity 17 is axially symmetrical with the structure of the first clearance cavity 16, so that the structure is symmetrical and can be installed without differentiation during packaging. The side of the base body 11 facing away from the second foam 20 is provided with a first accessory placement slot 18, an instruction manual placement slot 19, and a second accessory placement slot. The first accessory placement slot 18 and the second accessory placement slot are arranged opposite to each other, and the instruction manual placement slot 19 is located in the middle of the base body 11. The first accessory placement slot 18 has two square-shaped through slots 180 that penetrate the base body 11. These through slots 180 allow for the placement of accessories such as mounting plates without affecting the impact resistance and cushioning performance of the base body 11. The structure of the second accessory placement slot is the same as that of the first accessory placement slot 18. The instruction manual placement slot 19 is used to place instruction manuals, installation tools, etc.

[0042] In one embodiment, the structure of the second foam 20 is the same as that of the first foam 10, and both are integrally made of EPS material. At the same time, the symmetrical design of the first foam 10 and the second foam 20 facilitates packaging operations, eliminates the need for differentiation, and prevents incorrect or reversed foam packaging.

[0043] like Figure 2 and Figure 5 As shown, the side foam 30 is used to protect the sides of the product. Its two sides abut against the first foam 10 and the second foam 20 respectively to withstand and reduce the impact energy when the front, back, and sides of the product are impacted. The side foam 30 includes a side body 31 and abutment blocks 32 extending outwards from the ends of the side body 31. The side body 31 is provided with multiple buffer grooves 310 and gripping perforations 311. The buffer grooves 310 are strip-shaped grooves with a smaller inner surface and a larger outer surface, providing better cushioning. The buffer grooves 310 are arranged along one end of the side body 31 to the other. In one embodiment, the buffer grooves 310 are trapezoidal grooves, which are more likely to collapse and absorb energy, thereby reducing damage to the product's sides from physical impacts. The gripping perforations 311 are used to coordinate with the lifting positions of the box after packaging. There are two gripping perforations 311, each positioned opposite to the other.

[0044] The abutment block 32 abuts against the first supporting block 12 of the first foam 10 and the second foam 20. In one embodiment, the abutment block 32 has at least one second perforated hole 320 to protect the edges of the product. The second perforated hole 320 is generally elliptical in shape for better cushioning. Understandably, the second perforated hole 320 can also be other shapes of perforations to provide good cushioning. In this embodiment, there are two second perforated holes 320.

[0045] In one embodiment, the side foam 30 is integrally made of EPE material. Since the impact cushioning performance of EPE material is higher than that of EPS material, it can improve the impact cushioning performance of the side of the packaging structure and the front compression of the first and second foams 20, and has the effect of absorbing and decomposing energy.

[0046] In another embodiment, the present invention also provides a packaging box for a gas-fired heating and hot water boiler, the packaging box comprising a box body and the aforementioned cushioning packaging structure, the cushioning packaging structure being housed within the box body. Figure 6 As shown, the chimney outlet of the gas-fired heating and hot water boiler is located in the first clearance space 120 and within the buffer space 14. That is, the chimney outlet of the gas-fired heating and hot water boiler is within the protection range of the buffer packaging structure, which can avoid direct contact between the buffer packaging structure and the relatively fragile parts of the product.

[0047] Performance testing

[0048] A gas-fired heating and hot water boiler of model L1PB28-PT was packaged in the cushioning packaging structure of this invention, and a whole-unit drop test was conducted according to GB25034-2020 "Gas-fired Heating and Hot Water Boilers". The first foam 10 and the second foam 20 are provided with a first perforation 122 and a cushioning protrusion group 15, while the side foam 30 is provided with a second perforation 320 and a cushioning groove 310.

[0049] The drop test involves releasing the package at zero speed and allowing it to fall freely onto a flat, hard steel plate. The drop height is 500mm (the national standard is 304.8mm). The package is allowed to fall 10 times consecutively through six sides, three corners, and one corner. The package is then opened and its condition is inspected.

[0050] The inspection results showed that the outer packaging was free of cracks, damage, and severe deformation, and there was no leakage of goods (e.g., Figure 7 (As shown). All parts of the product are intact and the overall appearance is free of deformation, meeting the requirements.

[0051] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
